The gixxer and VStar are not geared to go an estimated 186 mph. Your $20k superbike is not the problem. Your riding style simply does not fit the characteristics of the bike. Try changing the sprockets if you want better low RPM throttle response. It WILL get hot no matter what you do... so get used to it. With more power comes more heat. You purchased one of the most powerful twin cylinder motorcycles on the market. What did you expect? It shares nothing in common with your gixxer 600 aside from maybe the front tire size. It is a different animal all together. I would LOVE to have an 1198s. You should feel lucky.
